Balancing Equations Practice Worksheet - Solve and balance ten chemical equations.

Here are the balanced chemical equations for your worksheet. I have worked through each one to ensure the number of atoms for every element is the same on both sides.

1) $2\text{NaNO}_3 + \text{PbO} \rightarrow \text{Pb(NO}_3)_2 + \text{Na}_2\text{O}$
*(Check: 2 Na, 2 N, 7 O, 1 Pb on both sides)*

2) $6\text{AgI} + \text{Fe}_2(\text{CO}_3)_3 \rightarrow 2\text{FeI}_3 + 3\text{Ag}_2\text{CO}_3$
*(Check: 6 Ag, 6 I, 2 Fe, 3 C, 9 O on both sides)*

3) $\text{C}_2\text{H}_4\text{O}_2 + 2\text{O}_2 \rightarrow 2\text{CO}_2 + 2\text{H}_2\text{O}$
*(Check: 2 C, 4 H, 6 O on both sides)*

4) $\text{ZnSO}_4 + \text{Li}_2\text{CO}_3 \rightarrow \text{ZnCO}_3 + \text{Li}_2\text{SO}_4$
*(Check: This equation was already balanced with coefficients of 1)*

5) $\text{V}_2\text{O}_5 + 5\text{CaS} \rightarrow 5\text{CaO} + \text{V}_2\text{S}_5$
*(Check: 2 V, 5 O, 5 Ca, 5 S on both sides)*

6) $\text{Mn(NO}_2)_2 + \text{BeCl}_2 \rightarrow \text{Be(NO}_2)_2 + \text{MnCl}_2$
*(Check: This equation was already balanced with coefficients of 1)*

7) $3\text{AgBr} + \text{GaPO}_4 \rightarrow \text{Ag}_3\text{PO}_4 + \text{GaBr}_3$
*(Check: 3 Ag, 3 Br, 1 Ga, 1 P, 4 O on both sides)*

8) $3\text{H}_2\text{SO}_4 + 2\text{B(OH)}_3 \rightarrow \text{B}_2(\text{SO}_4)_3 + 6\text{H}_2\text{O}$
*(Check: 6 H from acid + 6 H from base = 12 H total; 6 H in water x 2 = 12 H. Sulfur and Boron also match.)*

9) $\text{S}_8 + 8\text{O}_2 \rightarrow 8\text{SO}_2$
*(Check: 8 S, 16 O on both sides)*

10) $\text{Fe} + 2\text{AgNO}_3 \rightarrow \text{Fe(NO}_3)_2 + 2\text{Ag}$
*(Check: 1 Fe, 2 Ag, 2 N, 6 O on both sides)*
